ZeroAvia performed a 10-minute take a look at flight this week for it claims to be the world’s largest plane powered by a hydrogen-electric engine. The UK firm’s 19-seat Dornier 228 testbed plane has been retrofitted with a full-size prototype hydrogen-electric powertrain on the left wing. “That is the most important ZeroAvia engine examined up to now, and places the corporate on a direct path to a licensed configuration to be finalized and submitted for certification in 2023,” it mentioned. The plane has a 600 kW powertrain twin-engine on its left wing and a Honeywell TPE-331 inventory engine on the best. “The hydrogen-electric powertrain consists of two gas cell stacks, with a lithium-ion battery pack that gives peak energy assist throughout take-off and provides further redundancy for protected testing,” the corporate mentioned, which introduced that the hydrogen tanks and gas cell energy era techniques had been inserted into the cabin.

Chinese language researchers reported a superaerophilic / superaerophobic cooperative electrode that may enhance foam elimination in electrolyzers. The Chinese language Academy of Sciences and Beihang College researchers have launched titanium-based superaerophilic (SAL) stripes lined with fuel cushions on a platinum-based electrode. Superaerophobic (SAB) electrocatalytic areas encompass the SAL stripes. The stripes act as fuel channels to launch hydrogen. They famous that bubble adhesion to the electrode, bubble dispersion across the electrode, and poor dissolved hydrogen diffusion are widespread issues in electrolysis. “Benefiting from the improved mass switch, the overpotential for the SAL/SAB cooperative electrode at −10 mA cm−2 is just −19 mV, in comparison with −61 mV for the flat Pt electrode,” they wrote in Advances in Science.

Egypt-Japan College of Science and Expertise The researchers discovered that hydrogen manufacturing techniques primarily based on waste warmth techniques at 22.91% provide the best general effectivity. The effectivity of the system ranged from 11.6% to 22.91%, whereas the extent of worth of hydrogen (LCOH) ranged from $1.19/kg to $12.16/kg, the researchers mentioned. “The bottom worth is obtained when waste warmth is used, adopted by the grid, PV panels, and wind generators. Wind turbine techniques are usually not advisable on the market at costs of $8/kg and $10/kg,” they wrote. in a brand new one article on Vitality Conversion and Administration.

Centrica Enterprise Options is working with Germany’s 2G Vitality to supply clients with 100% hydrogen-ready mixed and warmth energy (CHP) techniques in the UK, Eire, the Netherlands, and Italy. “With a return on funding of lower than 12 months for some initiatives, ready-made hydrogen CHP stays a simple win to avoid wasting vitality,” SAYS the corporate primarily based in England.

Fusion Gas signed an offtake settlement with Portuguese pure fuel utility Dourogás for inexperienced hydrogen from its initiatives in Portugal. “This represents the primary Fusion Gas contract aimed toward mixing inexperienced hydrogen inside the Portuguese pure fuel grid,” SAYS the Irish firm. The Evora facility is prone to be commissioned this 12 months. The power is predicted to supply roughly 40 tons of inexperienced hydrogen per 12 months.

Hydrogen from France (HDF Vitality) signed a memorandum of understanding with the province of Kinshasa, Congo, to construct and function a inexperienced hydrogen photo voltaic plant. “That is the primary challenge of its variety deliberate in Central Africa,” mentioned HDF Vitality. It mentioned it was contemplating a location within the southern a part of the nation.
